The fall-out this morning from last night's historic debate for the White House finds many Democrats clearly worried.

Vice-President Kamala Harris defending President Biden's performance as one that got off to a "slow start" but had a "strong finish."

The 90-minute debate will likely be remembered first and foremost for a moment early in the debate when viewers found a raspy-voiced 81-year-old President Joe Biden saying this:

President Joe Biden: “We'd be able to help make sure that all those things we need to do, childcare, elder care, making sure that we continue to strengthen our health care system, making sure that we're able to make every single solitary person uh eligible for what I've been able to do with the, uh, with, with, with the COVID, excuse me, with, um, dealing with everything we have to do with, uh, what if we finally beat Medicare?"

Former President Donald Trump did not immediately respond to Biden’s apparent lost train of thought, but later on, on a different topic, he said this.

Former President Donald Trump: “I really don’t know what he said at the end of that sentence. I don’t think he knows what he said either.”

Other issues found the two completely at odds from inflation and immigration to abortion and democracy and found Jane Kleeb the head of the Nebraska Democratic Party insisting that, “Trump is a…liar. Every freaking word.”

Republican Congressman Don Bacon noting he’s been watching debates since 1976 and, “This is the most lopsided debate I’ve ever seen. Trump dominated tonight.”

But Trump’s critics look to this exchange to make the case that Trump is unfit to run the country.

Moderator: “As president, you swore an oath to quote, preserve, protect and defend unquote the constitution. What do you say to voters who believe that you violated that oath through your actions and inaction on January 6th and worry that you'll do it again."

Trump: "Well, I don't think too many believe that. And let me tell you about January 6th on January 6th, we had a great border. Nobody coming through very few on January 6th, we were energy independent on January 6th. We had the lowest taxes ever.

Moderator: “My question was, what do you say to those voters who believe that you violated your constitutional oath through your actions and in action on January 6th 2021 and worry that you'll do it again."

Trump: “Well, I didn't say that to anybody. I said peacefully and patriotically."

A second debate is scheduled for September.
